Is the child widget inside a layout?
If it is, the layout decides it size.
If you want to force the size of the widget inside the layout, you can sue setMinimumWidth() and setMinimumHeight().

Generally you should use setGeometry().

Just add a new child widget, or, draw directly on the widget where you want to have the graph.
